A trough-type distribution box consists of a pre-distribution trough, often called a parting box, mounted above several equally spaced narrow troughs. In a three-level configuration, the distributor includes three sets of metering elements or troughs, each designed to handle different liquid load conditions: minimum, design, and maximum flow rates . The troughs feature lateral notches or orifices that guide the liquid onto the packing or tray surface, ensuring uniform distribution . The parting box collects the incoming liquid and feeds it into the troughs. The troughs may have bottom holes or side openings, which help prevent fouling by allowing sediment to settle at the bottom while maintaining consistent flow through the orifices . Multi-level holes allow the distributor to operate efficiently across a wide range of flow rates, providing a high turndown ratio .
Liquid enters the parting box and is directed into the troughs. Each level of troughs is activated depending on the liquid load:
Trough-type three-level distributors are widely used in industries such as:
The trough-type three-level distribution box is a robust, versatile solution for distributing liquids in industrial columns. Its multi-level design allows it to handle varying flow rates efficiently, resist fouling, and maintain uniform coverage over packing or trays, making it ideal for high-capacity and demanding applications.
